It seems that for galax-ies to move the way they do, there has to be some "dark matter" out there, assuming Newton's Laws of Gravitation and Motion are valid. Something unseen is tugging on galaxies and the stars that comprise them. This is a sad situation, according to Moto Milgrom, an Israeli astrophysicist. Maybe there is nothing hidden and Newton's Law of Gravitation is wrong. After all, it was derived solely on the basis of solar-system observations. On a larger scale, it might be incorrect. Milgrom offers a startling alternative: for accelerations greater than a , let Newton's Law be; below that value, let the square of the acceleration be proportional to the mass of the attracting body and the inverse square of the distance. This done and presto the need for missing mass disappears. Even more remarkable is the fact that a particle with the acceleration a just reaches the speed of light over the age of the universe.

In pursuit of this missing mass, a U.S . team of astronomers has now detected previously unseen halos around several spiral galaxies. The halo luminosities are comparable to the brighter imbedded disks when integrated over a large area surrounding the galaxies. The halo masses, however, as inferred from the galaxies' rotation curves far exceed the masses of the bright spiral cores. The big question is "What are the dim but massive halos composed of?" They might consist of small, faint stars or nonluminous matter of some sort. The researchers had to conclude, though, that the halos are galactic components of "totally unknown nature."

New cosmic X-ray data from the satellite Ariel 5 suggests that a large, hitherto unsuspected mass is located in the same direction that the earth is moving. Thus, both X-ray and microwave data could be explained by supposing this mass to be large enough to pull the earth (and our Galaxy) toward it. This mass would have to be about 10 billion light years away and weigh as much as 100 million Galaxies. Such a gigantic blob or inhomogeneity in the universe would be very difficult to explain. As it is, the aggregation of stars into galaxies after the Big Bang remains poorly understood. The bigger the inhomogeneity, the harder it is to account for. The Big Bang should have spread matter out pretty evenly. (Anonymous; "Large Mass May Pull Earth Through Space," New Scientist, 83:21, 1979.)

A wider search undoubtedly would have netted many more, because dark matter is worrying a lot of astronomers. Observations of visible matter, the only kind we can see directly, suggest that most of the universe is, in fact, composed of dark matter. This conclusion comes mainly from the belief that something unseen (dark matter) is tugging on visible matter, making it do things the laws of motion say it should not do. All visible bodies, therefore, seem to be careening about in a dense cloud of unseen, unknown masses. These might be dark, Jupiter-sized objects, black holes, and/or some exotic forms of matter. We must choose between the reality of dark matter or admit that something is awry with our laws of gravitation and motion when they are applied on a cosmological scale Now, let us examine those four darkmatter items from the recent literature: D. Lin, a University of California astronomer, has shown that the Large Magellanic Cloud that orbits around our own galaxy (the Milky Way) is being torn apart (" cannibalized") by the powerful gravitational pull of a dense cloud of dark matter surrounding the Milky Way. This dismemberment of the Large Magellanic Cloud cannot be explained by the gravitational forces exerted by the stars in our galaxy that we can see. Lin calculates ...

Proponents of the Big Bang feel secure atop these pillars. But should they? A few Big-Bang skeptics, who have survived considerable establishment pressure, see growing cracks in those pillars. J. Narlikar identified two such cracks and, best of all, offered exciting remedies: (1 ) The redshift relationship, which works well with galaxies, falls apart when applied to quasars (see graphs); and (2 ) The background microwave radiation is much too smooth to come from the lumpy universe we observe. Narlikar opines as follows: Plot of red shift versus galaxy faintness supports the proposition that red shift is proportional to distance The same plot for quasars produces a scatter of points, suggesting that here red shifts have nothing to do with distance. "Given these problems, it is not a sound strategy to put all of our cosmic eggs in one big-bang basket. Rather, we should explore other possibilities.

If these two ratios are truly equal, then G must decrease with time. Beyond the unstable feeling one gets, there is nothing in physics or cosmology to discourage a belief in time-varying gravity. Indeed, some as-tronomical data weakly support the idea. It is geophysics, though, where one finds strong evidence. Measurements of the decreasing length of the day and the expansion of the earth give about the same value for a decreasing G -- after other contributing factors have been eliminated. An interesting consequence of all this is that astrophysical theory seems to require that a decreasing G be balanced by increasing mass. Experiments are now underway to detect the continual creation of mass in terrestrial objects. (Wesson, Paul S.; "Does Gravity Change with Time?" Physics Today, 33:32, July 1980.)

Duncan, BC. David Thompson was returning home at 8:30 PM, when he spotted a soccer-ball-size burning mass high over the trees. It landed in the road about 200 feet away, sounding like a light bulb popping. For about 3 seconds, it flamed. When approached, it was still sizzling, probably because the road was wet. The fallen substance quickly hardened, but samples were scraped off the asphalt. It turned out to be an odorless, rock-like substance. Left outside overnight, it had become soft by the next day and seemed to be melting. Samples were sent to Victoria for analysis. (Hausch, Karen; Cowichan Leader, March 15, 1984. Cr. L.

Normal galaxies seem to have masses of about 1011 times that of the sun. The unthinkable assumption suggests that every 108 years or so, these ordinary, unassuming galaxies become supermassive (about 1013 solar masses) for several million years. When the core of a galaxy becomes supermassive, its stars are tugged into tight new orbits. The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles. If particle physicists can (and must) evoke such magic, so can astronomers. (Clube, Victor; "Do We Need a Revolution in ...

Spaceships are always whisking off into hyperspace. But can we prove that more than three spatial dimensions exist? Shu-Yuan Chu, University of California at Riverside, has shown theoretically that in a five-dimensional world (4 of space, 1 of time) electric charge need not be conserved. This opens up an experimental avenue to test for an extra spatial dimension. For background, recall that physicists originally maintained that mass and energy had to be conserved separately. Then, Einstein came along to show that mass and energy could be interchanged, via E = mc2 , but that they had to be conserved together. In Shu-Yuan Chu's five-dimensional universe mass and charge can be interchanged, but their sum must be conserved. In other words, there exists an E = mc2 equivalent for mass and charge in five dimensions. We could look for this extra spatial dimension by looking for a particle that can be converted into another particle with the same mass+ charge, but made up of a different combination of mass and charge. If such reactions exist, we may be able to explore hyperspace in fact rather than in science fiction. (Gribbin, John; "Can Electric Charge Be Destroyed?" New Scientist, p. 16, October ...

The neutrino is now thought to come in three varieties -- electron neutrino, muon neutrino and tau neutrino. And a number of experiments are showing hints that a neutrino has a small mass and that it can oscillate from one variety to another." These experiments are not yet conclusive; and if the neutrino mass is not zero, it hardly weighs more than the grin of a Cheshire cat. But taken together, the laboratory results confirm that neutrinos are perplexing particles. Are they different entities or a single species wearing different costumes? The implications of the recent measurements are far-reaching: Physicists believe that there are a billion neutrinos around for each nucleon (proton, neutron, etc.) so that if neutrinos possess just a hint of mass, they will dominate the mass of the universe; and Measurements of solar neutrinos fall short by a factor of three of what theory says the sun should spew out. This discrepancy could be explained if the solar neutrinos change from electron neutrinos to another form during their flight from the sun to earth, for the terrestrial neutrino detectors measure only electron neutrinos.

Astronomers are now postulating a kind of cosmic 'string' that is very, very thin (10-30cm), enormously massive (1022 grams per centimeter), and very taut (1042 dynes tension). This string exists only in closed loops of infinite strands. Such string in loop form could have seeded galaxies and even black holes of solar mass. But these are not the major reasons why astronomers like the string hypothesis. It turns out that this bizarre string can tie the universe together gravitationally; that is, provide the long-sought 'missing mass.' The so-called 'missing-mass problem' is two-fold: Astronomers cannot see, with eye and instrument, enough mass to keep the universe from expanding indefinitely. If the kinetic energy of cosmic expansion is to be balanced by gravitational potential energy (an apparent philosophical imperative), we have so far identified only 15% of the required mass.

Infrared detectors have also picked up unidentified objects in the sky. These anomalies might all be explained by the existence of a large, dark planet with several moons -- or, if the mystery object turns out to be very far away, by a very large, dark stellar companion of our sun with its own system of planets. Several astronomers have been trying to pin down the properties of this Planet X or Massive Solar Companion (MSC). John P. Bagby has recently published a novel solution to this nagging puzzle in celestial mechanics. He suggests that the Massive Solar Companion is actually a distributed system; that is, appreciable mass also occupies the several stable Lagrangian points. The total MSC mass might be as much as half the sun's mass, perhaps 100 Astronomical Units (100 times the earth's distance from the sun.) If the MSC and its attendants are this massive, astronomers will have to revise the mass and density of the sun downward by a good bit.

Quasars, in fact, might be galaxies with spectacularly active centers. Would these unseeable black holes be the notorious "missing mass" in the universe? Not likely.

We frequently refer to this anomaly because at risk here is our basic theory of how stars work. Is our knowledge of stellar furnaces fundamentally in error or are some of the solar neutrinos somehow removed from the stream of neutrinos bound for earth? Recent calculations by Hans Bethe have brought sighs of relief to all astrophysicists. Without going into all of the details, Bethe finds that the interactions of the electron-neutrinos emitted by solar thermonuclear reactions with atoms constituting the solar mass change a substantial fraction of them into muonneutrinos. Since our terrestrial neutrino detectors register only electron-neutrinos, we may really be seeing only a fraction of the total number of neutrinos being emitted by the sun. If Bethe's calculations turn out to be correct, he may have eliminated a Class1 anomaly. But at a price!

Chyba has examined the lunar impact record and derived an estimate of the total mass of objects impacting the moon during the (hypothetical) period of heavy bombardment 3.8 to 4.5 billion years ago. This allowed him to calculate the mass influx for the earth during this period. His conclusion: if only about 10% of the incoming mass consisted of comets (mostly ice), the earth would have acquired all its ocean water. (Chyba, Christopher F.; "The Cometary Contribution to the Oceans of Primitive Earth," Nature, 330:632, 1987.) Comment. Frank claims that the earth today is continually bombarded by small icy comets, which down the eons may have kept the ocean basins full. So, we have two possible extraterrestrial sources of oceans -- both of a cometary nature.

Sepkoskiand and D. Raup, two researchers at the University of Chicago, have drawn up graphs showing the numbers of families of marine organisms that have vanished from the fossil rec ord over the eons. From this overview of manifest mass extinction emerged a puzzling and potentially profound pattern. Roughly every 26 million years over the last 250 million years, the number of extinctions jumped well above the background level. Some cyclic phenomenon seems to have been killing off life forms on a systematic basis. But no natural 26-million-year cycles are known although meteors and comets are favored causes of mass extinctions these days, they display no such cyclic period. (Simon, C.; "Pattern in Mass Extinctions," Science News, 124:212, 1983.) Comment. Instead of looking outward to astronomical catastrophism, perhaps we should look inward. The earth itself may undergo cyclic paroxysms; or life might undergo intrinsic phases of decline and rejuvenation. Periodic events in the evolutionary time scale. The 300-million-year cycle shown involves alternations between "icehouse" conditions (O ) and "greenhouse" conditions (G ). These may be due to changes in heat convention within the earth.

The foreshock (November 23) registered 4.8 ; the main shock (November 25), 6.5 mmlg. Many after-shocks followed. During this spate of tremors, 38 unusual luminosities were initially reported from the region, 8 of them before the foreshock, being in effect earthquake precursors. Afterwards, residents were queried for details and additional observations. A total of 46 reports sufficiently detailed for analysis were obtained. These luminous phenomena were classified according to a scheme proposed by F. Montandon in 1948. Montandon's five categories are: Seismic lightning (no thunder); Luminous bands in atmosphere; Globular incandescent masses; Fire tongues, small mobile flames near the ground, like will-o '- the wisps; and Flames emerging from the ground. The globular incandescent masses were by far the most common type of earthquake light during this Canadian "flap." Of these, F.

Do astronomers really observe black holes? The answer is: MAYBE. And even if YES, there are not nearly enough of them to satisfy theory. To illustrate, according to present theory, when stars weighing in at less than three solar masses collapse, they become neutron stars; if larger, the stars turn into small black holes. Theoretically, there should be one small black hole for every three neutron stars. But with some 500 neutron stars already pin-pointed, only 3 "possible" small black holes have been given votes of confidence; namely, Cyg X-1 , LMC X-3 , and AD 620-00.

Said universes are constituted of particles possessing properties so different from own own that we cannot normally discern the reality of these other "existences." In other words, astronomers cannot visually see the stars of these "shadow universes, nor do our detectors of electricity and magnetism acknowledge them. Normally, the subatomic "shadow" particles do not interact with our own particles either. Then, why even bother to contemplate shadow universes? Well, physicists say that none of their laws prohibits the existence of these other universes, and that's reason enough to search for a "looking-glass" entrance of some sort. Just suppose that the particles of one of these shadow universes do possess mass (or whatever shadow physicists call it). Some speculate that this shadow mass could be the "missing mass" that cosmologists have been looking for and can't find. Cosmologists need something palpable out there to explain the puzzling dynamics of galaxies and other phenomena. Some physicists in our universe have conceived of a situation where our universe may "rub together" with a shadow universe.

Thus, the outer planets of the solar system swing around the sun more slowly than the earth and the other inner planets. Astronomers always expected that the stars rotating around the massive hubs of the galaxies would obey these laws in a like manner. No such luck! Doppler measurements of galaxy rotations made by Vera C. Rubin and her colleagues, at the Carnegie Institution, indicate that most stars out near the galactic rims rotate just as fast or faster than those closer to the hub. Astronomers suppose that this anomalous rotation may be due to halos of undetected burntout stars and/or gas fringing the galaxies. Such halos would dis-tort the inverse-square-law field, permitting the observed anomalous rotation. (Anonymous; "Fast-Spinning Galaxies," Science Digest, 89:18, November 1981.) Comment.

Thus they would have burnt themselves out long ago, probably surviving as black holes. Such an ancient generation of massive stars can explain four puzzling features of the universe: (1 ) The amount and character of the background microwave radiation. (2 ) The identity of the "missing mass" needed to hold the universe together (i .e ., the relict black holes). (3 ) The primordial abundance of helium.

No deficit really exists because the neutrinos emitted by the sun change while in flight from a type that is easy to detect to a type that is difficult to register experimentally. The total number of neutrinos reaching the earth is what it should be according to theory but we have not been able to detect them all. This neutrino schizophrenia has now been confirmed, and our theory about how the sun works is safe. But the erasure of the solar-neutrinodeficit problem tells the particle physicists that neutrinos do indeed change type, which implies that they possess mass. But anomalies are sometimes contagious.

Certainly no figure-eight orbits have ever been observed in the cosmos so far, but who knows?. The situation becomes really bizarre when more than three equal masses are considered. A few of the many stable, but manifestly weird, configurations are also illustrated here. These are among the simplest. To illustrate, C. Simo has found a stable choreography for 799 bodies cavorting happily and stably together in space. And he was using only his laptop!

... to an old (534-millionyears-ago) crustal slippage, whereas Hapgood was talking about a cataclysm within the last 10,000 years or so. Nevertheless, it would have been nice to see Hapgood's earlier work acknowledged. Four features of this "new" proposal make it more palatable than Hapgood's to today's geologists and geophysicists: Two of the "new" authors, J. Kirschvink and D.A . Evans, are at the prestigious California Institute of Technology, while Hapgood was a PhD-less history professor at Keene State College. Status is important when theorizing. Kirschvink et al propose a scientifically acceptable mechanism for the onset of rapid crustal slippage. They visualize a huge chunk of the seafloor suddenly foundering and thereby changing the planet's mass distribution. This imbalance caused the continents to shift rapidly in order to restore the smooth rotation of the earth around its spin axis. Within a period of 15 million years, they envisage, the continents had slipped about 90 . Part of what is now North America moved from the South Pole to near the Equator. Evidence for this huge shift is seen in measurements of the earth's magnetic field frozen in the rocks. In other words, Kirschvink et al used the methods of paleomagnetism. The "new" crustal slippage is really only accelerated continental drift (a dominant and well-established paradigm) and not the more radical notion of the entire outer layer of crust slipping over the earth's mantle like a greased onion skin. Nor is the proposed process anything like poleflipping ...

... the papers were full of still another claim that a black hole had been found. This time there was no doubt; this was it; a bona fide, undeniable black hole. The search was finally over! Later, though, this claim was muted to: "the best evidence yet for a black hole." [Remember that no light escapes a black hole; you cannot see it directly. It is detected only through its effects on nearby observable matter.] Despite what the theorists fervently believe, black holes may not be lurking out there in space, unseen, but still able to gobble up matter and unwary alien spacecraft. For example, consider the following iconoclastic tidbit: "A gigantic, exceptionally bright star that scientists thought could become a black hole is actually shedding mass at such an astonishing rate that it eventually will disappear, a discovery that casts doubt on theories of stellar evolution, a researcher reports. "' If such massive stars are losing mass at such a prodigious rate, they will not form black holes but will peel off to virtually nothing,' Sally Heap, a NASA astronomer, said yesterday at a national meeting of the American Astronomical Society." In other words, the accepted means of black hole production -- and, therefore, black holes themselves -- still seem to be in observational limbo.

Science Frontiers ONLINE No. 1: September 1977 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Cattle Mutilations Called Episode Of Collective Delusion During the past several years, farmers in the western states have been reporting dead cattle that seemed strangely mutilated. Soft, exposed parts, such as the ears and genitals, were apparently removed with surgical precision. Some corpses seemed bloodless. Local papers blamed satan worshippers and UFO occupants. This paper analyzes the 1974 mutilation "flaps" in South Dakota and Nebraska, with special attention to the rapid rise and equally rapid decline of public interest as measured by newspaper coverage. In the opinion of the author, these two episodes are classic cases of mild mass hysteria, similar to the occasional crazes of automobile window-pitting. In all cases where university veterinarians examined the corpses, the mutilations were ascribed to small predatory animals. The veterinarians also pointed out that blood coagulates in a couple days after death, accounting for the frequent "bloodless" condition. With such expert reassurances, the "mass delusions" subsided quickly. Cattle mutilation flaps are thus seen by the author as episodes when people interpret the mundane in bizarre new ways, due perhaps to cultural tensions. It is noted, however, that expert veterinarians examined only a few of the dozens of mutilations, and that some people rejected the above commonplace explanations.

Science Frontiers ONLINE No. 61: Jan-Feb 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Synchronous Rhythmic Flashing Of Fireflies We humans are pretty smug about our ability to communicate complex messages via sound waves. Of course, we recognize that whales and other cetaceans also seem to "talk" to one another, and that other animals employ their sense of smell for relaying messages. But most of us do not realize that lowly fireflies congregate to communicate en masse, with untold thousands of individuals cooperating in huge synchronized light displays. In reading some of the descriptions of these great natural phenomena, one recalls the light displays used to communicate with the aliens in the movie Close Encounters of the Third Kind . J. Buck has been studying flashing fireflies for over half a century. In fact, his first review paper was published in 1938. Buck has now brought that paper up to date in the current Quarterly Review of Biology with a 24page contribution. It is difficult to do justice to this impressive work in a newsletter. Our readers will have to be satisfied with a mere two paragraphs, in which Buck summarizes some of the incredible synchronies. "More than three centuries later Porter observed a very different behavior in far southwestern Indiana in which, from the ends of a long row of tall riverbank trees, synchronized flashes '. .. began moving toward each other, met at the middle, crossed and traveled to the ends, as when two pebbles are dropped simultaneously into the ends of a long narrow tank of water ...

... Sourcebook Project Sourcebook Subjects A New Cosmic Heresy Often the simplest of observations will have the most profound consequences. It has long been a cornerstone of modern science, to say nothing of man's cosmic outlook, that the earth attends a modest star that shines in an undistinguished part of a run-of-the-mill galaxy. Life arose spontaneously and man evolved on this miscellaneous clump of matter and now directs his own destiny without outside help. This cosmic model is supported by the Big-Bang and Expanding Universe concepts, which in turn are buttressed by the simple observation that astronomers see redshifts wherever they look. These redshifts are due, of course, to matter flying away from us under the impetus of the Big Bang. But redshifts can also arise from the gravitational attraction of mass. If the earth were at the center of the universe, the attraction of the surrounding mass of stars would also produce redshifts wherever we looked! The argument advanced by George Ellis in this article is more complex than this, but his basic thrust is to put man back into a favored position in the cosmos. His new theory seems quite consistent with our astronomical observations, even though it clashes with the thought that we are godless and making it on our own. (Davies, P.C .W .; "Cosmic Heresy?"

The thought that a spinning mass might lose weight was just too horible to contemplate. Two replications of the Japanese experiment have been reported so far. "James E. Faller and his colleagues at the Joint Institute for Laboratory Astrophysics in Boulder, Colo., repeated the Japanese experiment by looking for signs of weight loss in a spinning gyroscope consisting of a brass top about 2 inches in diameter sealed in a small plastic chamber. 'We conclude that within our experimental sensitivity, which is approximately 35 times larger than needed to see the effect reported...there is no weight change of the type...described.'" (Anonymous; "An Absence of Antigravity," Science News, 137:127, 1990. Cr. F. Hanisch) "Now T.J . Quinn and A. Picard of the International Bureau of Weights and Measures in Sevres Cedex, France, have repeated the experiment. They find changes in the apparent mass of their gyroscope that depend on the speed and sense of rotation, but they amount to only about 5 per cent of the effect reported by Hayasaka and Takeuchi."
